Overall, the System Sensor B224BI-WH Isolator bases allow the Signaling Line Circuit (SLC) loop to operate under fault conditions created from a short circuit preventing an entire communication loop from being disabled. Also, the System Sensor B224BI-WH base isolates the section of the loop containing the short circuit from the remainder of the circuit and automatically restores when the fault is correct.

System Sensor offers standard 4″ and 6″ bases, as well as, specialty base designs including relay, isolator, sounder, and low-frequency sounder options for Select Series detectors. Besides, the standard 4″ and 6″ bases offer a plug-in detector base intended for use in intelligent systems, with screw terminals provided for power (+ and –), and remote annunciator connections. Communication takes place over the power (+ and –) lines. The 4″ base offers a compact design while the 6″ base provides compatibility with a wider range of junction boxes.
